Abstract

An agricultural soil cultivation device comprising at least ground roller provided with tyre elements rolling on the ground. Some of the tyre elements can be used as a travelling device for transporting the soil cultivation device on roads and can be placed in a downward protruding position in relation to the other tyre elements. In order to use individual roller elements, which are arranged in the levelling system of soil cultivation devices which are provided with rollers and which have levelling systems, for additional transport purposes, the roller consists of several tyre elements which are arranged next to each other and which are respectively disposed on individual pivoting arms, whereby the height thereof can be adjusted in relation to each other, on a supporting beam which extends in crosswise manner. At least one pressure compensation system is associated with the individual pivoting arms. The pressure compensation system is embodied in such a way that the tyre elements forming the travelling device for transport are impinged upon with higher pressure than the other tyre elements in the levelling system.

Description

Die Erfindung betrifft ein landwirtschaftliches Bearbeitungsgerät gemäß des Oberbegriffes des Patentanspruches 1.The invention relates to an agricultural processing apparatus according to the preamble of claim 1.

Ein derartiges Bearbeitungsgerät ist in der nicht vorveröffentlichten deutschen Patentanmeldung P 101 41 991.0 beschrieben. Bei diesem Bodenbearbeitungsgerät sind die das Fahrwerk bildenden Reifenelemente auf Höhe der übrigen die die Walze bildenden Reifenelemente angeordnet, so dass eine möglichst kurze und kompakte Bauweise des Gerätes erreicht wird. Die das Fahrwerk bildenden Reifenelemente weisen einen größeren Durchmesser als die übrigen Reifenelemente der Walze auf. Die einzelnen Abschnitte der Walze sind jeweils höhenunveränderlich gegenüber dem Tragrahmen der Walze angeordnet. Die das Fahrwerk bildenden Reifenelemente der Walze sind mittels Schwingen an dem Rahmen des Gerätes angeordnet und können mittels Hydraulikzylinder gegenüber den übrigen Elementen der Walze abgesenkt bzw. auf Höhe der übrigen Reifenelemente der Walze gebracht werden. Zum Transport des Gerätes werden die das Fahrwerk bildenden Reifenelemente mittels der Hydraulikzylinder gegenüber den übrigen Reifenelementen nach unten gedrückt, so dass das Gerät angehoben wird.Such a processing device is not pre-published in the German Patent Application P 101 41 991.0 described. In this harrow, the tire forming the chassis elements at the level of the rest of the roller forming the tire elements are arranged so that the shortest and most compact design of the device is achieved. The chassis forming tire elements have a larger diameter than the other tire elements of the roller. The individual sections of the roller are each arranged höhenunveränderlich opposite the support frame of the roller. The wheel forming the tire elements of the roller are arranged by means of rocking on the frame of the device and can be lowered by means of hydraulic cylinder relative to the other elements of the roller or brought to the height of the other tire elements of the roller. To transport the device, the tire elements forming the chassis are pressed down by means of the hydraulic cylinders relative to the other tire elements, so that the device is lifted.

Durch das deutsche Gebrauchsmuster 90 010 178 ist gemäß des die Seiten 11 und 12 überbrückenden Absatzes eine aus einzelnen und zueinander beweglichen Reifenelementen bestehende Walze bekannt, der ein hydraulisches bzw. hydropneumatisches Ausgleichssystem zugeordnet ist. Durch diese Ausgleichsanordnung der hydraulischen bzw. hydropneumatischen Federaggregate kann auch auf unebenen Böden eine besonders ruhige Fahrt der Bodenwalze und der davon getragenen Geräteteile erreicht werden.By the German utility model 90 010 178 According to the paragraph bridging the sides 11 and 12, a roll consisting of individual and mutually movable tire elements is known, to which a hydraulic or hydropneumatic compensation system is assigned. By this balancing arrangement of the hydraulic or hydropneumatic spring units can be achieved even on uneven floors a particularly smooth ride the bottom roller and the device parts carried by it.

Bei einer derartigen Bodenwalze können einzelne Reifenelemente aufgrund des Ausgleichssystems nicht ohne weiteres als Transportfahrwerk genutzt werden.In such a bottom roller individual tire elements can not be readily used as a transport undercarriage due to the compensation system.

Der Erfindung liegt die Aufgabe zugrunde, bei Bodenbearbeitungsgeräten mit Walzen, die Ausgleichssysteme aufweisen, einzelne in dem Ausgleichssystem angeordnete Walzenelemente auch für den Transport nutzbar zu machen.The invention has for its object to make available in tillage equipment with rollers having balancing systems, arranged in the compensation system roller elements for transport.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Infolge dieser Maßnahmen können durch eine zusätzliche Druckbeaufschlagung einzelner Reifenelemente der Walze diese Reifenelemente über das Druckausgleichssystem gegenüber den übrigen Reifenelementen abgesenkt und somit die gesamte Maschine zum Transport angehoben werden. Das hydraulische Ausgleichssystem wird dazu genutzt, um im Mittelbereich der Maschine die jeweiligen zur Straßenfahrt genutzten Reifenelemente der Walze stärker zu belasten, somit trägt sich die Maschine nur auf diesen Reifenelementen. Hierdurch wird der übrige Mittelbereich und der Außenbereich der Walze während der Straßenfahrt entlastet bzw. ganz ausgehoben.This object is achieved by the characterizing features of claim 1. As a result of these measures can be lowered by an additional pressurization of individual tire elements of the roller these tire elements on the pressure compensation system over the other tire elements and thus the entire machine can be lifted for transport. The hydraulic balancing system is used to load more heavily in the center region of the machine, the respective tire elements of the roller used for road travel, thus, the machine carries only on these tire elements. As a result, the rest of the middle area and the outer area of the roller is relieved during road travel or completely dug.

Insbesondere bei längeren Transportfahrten ist es vorteilhaft, dass die für den Transport vorgesehenen Reifenelemente mit Druckluft beaufschlagbar sind. Hierzu ist es möglich, eine Reifendruckregelanlage vorzusehen mittels welcher die Reifenelemente für die Transportfahrt mit einem vorteilhaften Luftdruck beaufschlagt werden können, während für die Bearbeitung auf dem Felde der Luftdruck abgesenkt wird.In particular, for longer transport trips, it is advantageous that the tire elements provided for the transport can be acted upon with compressed air. For this purpose, it is possible to provide a tire pressure control system by means of which the tire elements for the transport journey can be acted upon with an advantageous air pressure, while for the processing on the field, the air pressure is lowered.

Um die einzelnen Reifenelemente, die für die Transportfahrt vorgesehen sind, mit einem höheren Druck in dem Ausgleichssystem gegenüber den übrigen Reifenelementen beaufschlagen zu können, sind in den Hydraulikleitungen des Ausgleichssystems Absperrventile angeordnet.To be able to act on the individual tire elements, which are provided for the transport journey, with a higher pressure in the compensation system compared to the other tire elements, shut-off valves are arranged in the hydraulic lines of the compensation system.

Für manche Einsatzfälle kann es sinnvoll sein zumindest das Fahrwerk bildende Reifenelementen Abstreifer zuzuordnen. Diese Abstreifer streifen das an der Lauffläche oder zwischen den Reifenelemente anhaftende Bodenteile von diesen ab.For some applications, it may be useful to assign at least the chassis forming tire elements scrapers. These scrapers strip the adhering to the tread or between the tire elements of these parts.

Weitere Einzelheiten der Erfindung sind den übrigen Ansprüchen, der Beispielsbeschreibung und den Zeichnungen zu entnehmen.Further details of the invention can be taken from the remaining claims, the example description and the drawings.

Die Bodenwalze 1 kann als separates Bodenbearbeitungsgerät eingesetzt werden. Des weiteren ist auch vorgesehen, dass die Bodenwalze 1 als Nachlauf- und Tiefenführungselement eines vorlaufenden Bodenbearbeitungsgerätes, Bestandteil einer Geräte- oder Bestellkombination oder vorlaufendes Verdichtungselement für Säschare ist.The bottom roller 1 can be used as a separate harrow. Furthermore, it is also provided that the bottom roller 1 as a caster and depth guide element of a leading tillage equipment, part of a device or order combination or leading compression element for coulters.

Die Bodenwalze 1 weist den Rahmen 2 auf, der den quer zur Fahrtrichtung 3 laufenden Querbalken 4 aufweist. An dem Querbalken 4 sind über Gummifederelemente 5 aufweisende Gelenkelemente 6 die sich nach schräg hinten unten erstreckenden Tragarme 7 federnd schwenkbar angeordnet sind, an denen die Rollen 8 oder reifenartigen Elemente der Walze 1 angeordnet sind. Diese Elemente 7 sind in Fahrtrichtung 3 versetzt zueinander angeordnet, wie die Fig. 4 zeigt. Zwischen dem Rahmen 2 und den Tragarmen 5 ist jeweils ein Hydraulikzylinder 9 angeordnet. Die Hydraulikzylinder 9 sind als Druckausgleichssystem zwischen den einzelnen reifen- und walzenartigen Elementen 8 ausgebildet. Das Druckausgleichssystem weist zwei Druckausgleichskreise 10 und 11 auf, wie die Fig. 1 zeigt. Die Reifenelemente 8 der Bodenwalze 1 rollen während der Bodenbearbeitung auf dem Boden ab. Zum Transport des Bodenbearbeitungsgerätes können einige der Reifenelemente 8' gegenüber den übrigen Reifenelementen 8 nach unten gedrückt werden und somit als Fahrwerk 11 dienen. Somit können einige Reifenelemente 8' als Fahrwerk 11 zum Transport des Gerätes auf der Straße nutzbar gemacht werden und gegenüber den übrigen Reifenelementen 8 eine die übrigen Reifenelementen 8 nach unten überragende Position gebracht werden, wie die Fig. 1 und 2 zeigen.The bottom roller 1 has the frame 2, which has transverse to the direction of travel 3 transverse bar 4. On the crossbar 4 are over rubber spring elements 5 having joint elements 6 which are obliquely behind downwardly extending support arms 7 are arranged resiliently pivotable, on which the rollers 8 or tire-like elements of the roller 1 are arranged. These elements 7 are offset from one another in the direction of travel 3, as the Fig. 4 shows. Between the frame 2 and the support arms 5, a hydraulic cylinder 9 is arranged in each case. The hydraulic cylinders 9 are formed as a pressure equalization system between the individual tire and roller-like elements 8. The pressure compensation system has two pressure compensation circuits 10 and 11, like the Fig. 1 shows. The tire elements 8 of the bottom roll 1 roll off during soil tillage on the ground. For transporting the harrow, some of the tire elements 8 'can be pressed downwards relative to the other tire elements 8 and thus serve as a chassis 11. Thus, some tire elements 8 'can be used as a chassis 11 for transporting the device on the road and compared to the other tire elements 8, the rest of the tire elements 8 downwardly superior position are brought, like the Fig. 1 and 2 demonstrate.

Hierzu sind in jedem Druckausgleichskreis 10 und 10' des Druckausgleichssystems Sperrventile 12,12', 13, 13' und jeweils ein Ausgleichszylinder 14, 14' angeordnet, wie Fig. 1 zeigt. Die Hydraulikzylinder 9, 9' jedes Druckausgleichkreises sind über die Leitungen 15 miteinander verbunden. In diesen Leitungen 15 sind die Absperrventile 12, 12', 13, 13' und die Ausgleichszylinder 14, 14' angeordnet, wie Fig. 1 zeigt. Die den als Fahrwerk 11 dienenden Reifenelementen 8' zugeordneten Hydraulikzylinder 9' sind gegenüber den übrigen Hydraulikzylindern 9 mittels der Absperrventile 12, 12' absperrbar. Des weiteren ist jedem Hydraulikdruckausgleichssystem 10, 10' ein Ausgleichszylinder 14, 14' zugeordnet, um so über das geschlossene Druckausgleichssystem 10, 10' eine zusätzliche Ölmenge in die den als Fahrwerk 11 dienenden Reifenelementen 8' zugeordneten Hydraulikzylindern 9' zu drücken, damit die als Fahrwerk 11 dienenden Reifenelemente 8' nach unten gedrückt werden und so die Maschine vom Boden abgehoben werden kann. Die Ausgleichszylinder 14,14' sind über die Leitungen 15' an eine Hydraulikanlage, beispielsweise die das Bodenbearbeitungsgerät ziehenden Ackerschleppers angeschlossen. Des weiteren ist in den von den Ausgleichzylinder 14, 14' zu der Hydraulikanlage, die beispielsweise die des Schleppers oder eine separate Hydraulikanlage sein kann, führende Leitungen 15', jeweils ein weiteres Sperrventil 13, 13' angeordnet, wie Fig. 1 zeigt, um sicher zu stellen, das während des Transportes kein Öl aus die als Fahrwerk 11 dienenden Reifenelementen 8' zugeordneten Hydraulikzylindern 9' entweichen kann.For this purpose, in each pressure compensation circuit 10 and 10 'of the pressure compensation system shut-off valves 12,12', 13, 13 'and in each case a compensating cylinder 14, 14' are arranged, such as Fig. 1 shows. The hydraulic cylinders 9, 9 'of each pressure compensation circuit are connected to one another via the lines 15. In these lines 15, the shut-off valves 12, 12 ', 13, 13' and the compensating cylinders 14, 14 'are arranged, such as Fig. 1 shows. The serving as a chassis 11 tire elements 8 'associated hydraulic cylinder 9' are compared to the other hydraulic cylinders 9 by means of the shut-off valves 12, 12 'shut off. Furthermore, each hydraulic pressure equalization system 10, 10 'associated with a compensating cylinder 14, 14' so as to press on the closed pressure compensation system 10, 10 'an additional amount of oil in serving as the chassis 11 tire elements 8' associated hydraulic cylinders 9 ', so that as Suspension 11 serving tire elements 8 'are pressed down and so the machine can be lifted off the ground. The compensating cylinders 14,14 'are connected via the lines 15' to a hydraulic system, for example, the tillage tractor pulling tractor. Furthermore, in the of the compensation cylinder 14, 14 'to the hydraulic system, which may be, for example, that of the tractor or a separate hydraulic system, leading lines 15', in each case a further shut-off valve 13, 13 'are arranged Fig. 1 shows to make sure that during transport no oil from the suspension 11 serving as tire elements 8 'associated hydraulic cylinders 9' can escape.

Aufgrund dieser Ausgestaltung des Druckausgleichsystems 10, 10' können für den Transport die für den Transport das Fahrwerk 11 bildenden Reifenelementen 8' zugeordneten Hydraulikzylindern 9' mit einem höheren Druck in dem Ausgleichssystem 10, 10' als die übrigen Reifenelemente 8 in dem Ausgleichsystem zugeordneten Hydraulikzylindern 9 beaufschlagt werden.On account of this design of the pressure compensation system 10, 10 ', the hydraulic cylinders 9' assigned to the chassis 11 for transporting the chassis 11 can be provided with a higher pressure in the compensation system 10, 10 'than the remaining tire elements 8 in the hydraulic system assigned to the compensation system 9 be charged.

Wenn die einzelnen die das Fahrwerk 11 bildenden Reifenelemente 8' als Hohlreifen ausgebildet sind, ist es möglich diese Reifenelemente 8' für den Transport mit Druckluft zu beaufschlagen. Hierbei sind die für den Transport vorgesehenen Reifenelemente 8' mit einem höheren oder gleichen Luftdruck, als die übrigen Reifenelemente 8 beaufschlagbar.If the individual the chassis 11 forming the tire elements 8 'are formed as a hollow tire, it is possible to apply these tire elements 8' for transport with compressed air. Here, the intended for transporting the tire elements 8 'with a higher or the same air pressure, as the other tire elements 8 acted upon.

In einfacher Weise lässt sich diese Druckluftbeaufschlagung verwirklichen, indem zumindest den Reifenelementen 8' ein nicht dargestelltes Luftdruckregelsystem zugeordnet ist.In a simple way, this compressed air can be realized by at least the tire elements 8 'associated with an unillustrated air pressure control system.

Die das Fahrwerk 11 bildenden Reifenelemente 8' sind zumindest teilweise mit einer nicht dargestellten Bremsanlage ausgestattet.The chassis 11 forming the tire elements 8 'are at least partially equipped with a brake system, not shown.

Die Funktionsweise des Druckausgleichssystems 10, 10' mit Transporteinrichtung oder Fahrwerk 11 ist folgende:The operation of the pressure compensation system 10, 10 'with transport device or chassis 11 is the following:

Die in den Druckausgleichssystemen 10, 10' angeordneten Absperrventile 12, 12', 13, 13' befinden sich in Öffnungsstellung, so dass das Öl von den einzelnen Zylindern 9 durch die Absperrventile strömen kann. Somit können die einzelnen Zylinder 9 des linken Druckausgleichssystems 10 sich zueinander bewegen, genauso wie die Zylinder 9' des rechten Druckausgleichssystems 10'. Während der Arbeit auf dem Felde ist die zusätzliche Ölmenge, die zur Schaffung des Fahrwerkes 11 benötigt wird, in dem jeweiligen Fahrwerksausgleichszylinder 14, 14' enthalten.The shut-off valves 12, 12 ', 13, 13' arranged in the pressure compensation systems 10, 10 'are in the open position, so that the oil from the individual cylinders 9 can flow through the shut-off valves. Thus, the individual cylinders 9 of the left pressure equalization system 10 can move relative to one another, as can the cylinders 9 'of the right pressure equalization system 10'. While working in the field, the additional amount of oil needed to create the landing gear 11 is contained in the respective undercarriage jack 14, 14 '.

Wenn nun die Maschine in Transportstellung gebracht werden soll, um auf dem Fahrwerk 11 transportiert zu werden, werden zunächst die Absperrventile 12, 12' in den Druckausgleichssystemen 10, 10' in Sperrstellung gebracht, so dass kein Öl von dem Fahrwerk 11 zugeordneten Reifenelementen 8' zugeordneten Hydraulikzylindern 9' in die übrigen Hydraulikzylinder 9 fließen kann. Die Absperrventile 13, 13', welche zwischen dem Fahrwerksausgleichszylinder 14, 14' und der Hydraulikanlage angeordnet sind, befinden sich in Öffnungs- bzw. Durchflussstellung, so dass über die Hydraulikanlage und das jeweilige Absperrventil 13, 13' Öl in den jeweiligen Ausgleichszylinder 14, 14' gedrückt werden kann. Über den jeweiligen Ausgleichszylinder 14, 14' wird Öl in das geschlossene Hydrauliksystem der Fahrwerkszylinder 9' gedrückt, so dass die Hydraulikzylinder 9' ausfahren und die das Fahrwerk 11 bildenden Reifenelemente 8' nach unten drücken.If now the machine is to be brought into the transport position to be transported on the chassis 11, first the shut-off valves 12, 12 'placed in the pressure compensation systems 10, 10' in blocking position, so that no oil from the chassis 11 associated tire elements 8 ' associated hydraulic cylinders 9 'in the remaining hydraulic cylinder 9 can flow. The shut-off valves 13, 13 ', which are arranged between the chassis compensation cylinder 14, 14' and the hydraulic system, are in the opening or flow position, so that via the hydraulic system and the respective shut-off valve 13, 13 'oil in the respective balancing cylinder 14, 14 'can be pressed. Oil is pressed into the closed hydraulic system of the chassis cylinders 9 'via the respective compensating cylinder 14, 14', so that the hydraulic cylinders 9 'extend and the tire elements 8' forming the chassis 11 press downwards.

Wenn die Reifenelemente 8' ganz nach unten gedrückt sind, werden die Absperrventile 13, 13' geschlossen, so dass kein Öl entweichen kann. Die Maschine lässt sich dann mit dem Fahrwerk 11 auf Straßen und Wegen transportieren.When the tire elements 8 'are pressed all the way down, the shut-off valves 13, 13' are closed, so that no oil can escape. The machine can then be transported with the chassis 11 on roads and paths.

Wenn die Maschine dann anschließend aus Transport- in Arbeitsstellung gebracht werden soll, werden die Absperrventile 13 und 13' wiederum geöffnet, so dass das Ölvolumen über den jeweiligen Ausgleichszylinder 14, 14' ausgeglichen werden kann, so dass die dem Fahrwerk 11 zugeordneten Hydraulikzylinder 9' einfahren und das Öl aus dem Ausgleichszylinder 14, 14' in die Hydraulikanlage zurückströmt. Weiterhin werden dann noch die Absperrventile 12, 12' geöffnet, so dass das Druckausgleichssysteme 10 und 10' für die Arbeit wieder in Funktion ist.When the machine is then to be subsequently brought from transport to working position, the shut-off valves 13 and 13 'are in turn opened, so that the oil volume can be compensated via the respective compensating cylinder 14, 14' so that the hydraulic cylinder 9 'assigned to the chassis 11 is compensated. retract and the oil from the compensating cylinder 14, 14 'flows back into the hydraulic system. Furthermore, then the shut-off valves 12, 12 'are opened, so that the pressure compensation systems 10 and 10' is back to work for the work.

Mittels dieser vorbeschriebenen Ausbildung des Hydraulikdruckausgleichssystems 10, 10' lässt sich eine Integration des Fahrwerkes 11 für Straßenfahrten in die Walze 1 erreichen. Das hydraulische Ausgleichssystem 10, 10' wird genutzt, um den Mittelbereich der Maschine und den jeweiligen zur Straßenfahrt genutzten Bereich 8' der Walze 1 stärker zu belasten, somit trägt sich die Maschine auf diesen Rollen 8'. Es wird somit ein simuliertes Fahrwerk 11 erreicht, der Mittelbereich zwischen diesen Rollen 8' wird während der Straßenfahrt entlastet bzw. gegenüber den das Fahrwerk 11 bildenden Reifenelementen 8' angehoben. Dies bedingt, dass Maschinen für große Arbeitsbreiten von der Klapptechnik her eine Dreiteiligkeit besitzen, und zwar für den Mittelbereich in dem auch die Fahrwerksrollen 8' untergebracht sind und ein linkes und rechtes Klappteil, das während der Straßenfahrt hochgeklappt werden kann, was jedoch nicht in den Zeichnungen dargestellt ist. Es besteht auch die Möglichkeit, dass die Rollen 8', auf der die Maschine während der Straßenfahrt sich abstützt, einen gewissen Versatz zueinander haben, wie die Fig. 3 und 4 zeigen.By means of this above-described design of the hydraulic pressure compensation system 10, 10 'can be an integration of the chassis 11 for road driving in the roller 1 reach. The hydraulic balancing system 10, 10 'is used to load the central area of the machine and the respective area 8' of the roller 1 used for road travel more heavily, thus the machine bears on these rollers 8 '. It is thus achieved a simulated chassis 11, the middle area between these rollers 8 'is relieved during road travel or compared to the chassis 11 forming tire elements 8' raised. This implies that machines for large working widths of the folding technology ago have a three-piece, for the central area in which the suspension rollers 8 'are housed and a left and right folding part, which can be folded up while driving on the road, but not in the Drawings is shown. There is also the possibility that the rollers 8 ', on which the machine is supported during road travel, have a certain offset from each other, like the Fig. 3 and 4 demonstrate.

Diese Rollen 8' können luftbereift sein, oder nur während der Straßenfahrt beispielsweise über ein nicht dargestelltes Druckregelsystem mit Luft gefüllt werden. Wie bereits vor ausgeführt, können alle oder einige Rollenelemente des Fahrwerks 11 mit einer nicht dargestellten Bremseinrichtung ausgestattet sein. Die Walzenelemente sind so ausgebildet, dass die übrigen Walzenelemente 8 und das Fahrwerk 11 bildenden Reifenelemente 8' im Walzenbereich während der Arbeit ein nahezu ähnliches Arbeitsergebnis auf dem Acker erzeugen. Das Fahrwerk 11 soll nicht nur zum Straßentransport, sondern auch zum Manövrieren am Vorgewende auf dem Felde zur Verfügung stehen.These rollers 8 'may be pneumatic, or may only be filled with air during road travel, for example via an unillustrated pressure control system. As already stated before, all or some roller elements of the chassis 11 may be equipped with a braking device, not shown. The roller elements are designed so that the other roller elements 8 and the chassis 11 forming tire elements 8 'in the roll area during work produce a nearly similar work result on the field. The chassis 11 is not only for road transport, but also for maneuvering on the headland in the field are available.

Das Fahrwerk 11 kann unterschiedlich ausgeführt sein, es könnten, wie im Ausführungsbeispiel gezeigt jeweils vier Rollen 8' vorgesehen sein oder auch nur zwei Rollen 8'. Es ist auch möglich durch eine entsprechende Anordnung von Absperrventilen 12, 12' für die Straßenfahrt jeweils nur zwei Rollen 8' zu nutzen.The chassis 11 may be designed differently, it could, as shown in the embodiment, four roles 8 'may be provided or even two rollers 8'. It is also possible by an appropriate arrangement of shut-off valves 12, 12 'for road travel in each case only two rollers 8' to use.

Die Bodenwalze 16 gemäß den Fig. 5 bis 11 unterscheidet sich von der Bodenwalze 1 gemäß den Fig. 1 bis 4 im wesentlichen dadurch, dass hinter der Bodenwalze 16 Säschare angeordnet sind und die Rahmen 18 an einem zentralen Tragrahmen 19 befestigt sind. Hierbei sind die Rahmen 18', welche die Reifenelemente 8', die das Fahrwerk 11 bilden, mittels einer Gelenkanordnung 20 am Tragrahmen 19 befestigt sind und mittels Hydraulikzylinder 21 um die Gelenkachse 22 dieser Gelenkanordnung 20 verschwenkbar sind, während die übrigen Rahmen 18 an dem Tragrahmen 19 starr angeordnet sind.The bottom roller 16 according to the Fig. 5 to 11 differs from the bottom roll 1 according to the Fig. 1 to 4 essentially characterized in that behind the bottom roller 16 coulters are arranged and the frame 18 are fixed to a central support frame 19. Here are the frame 18 ', which are the tire elements 8', which form the chassis 11 are fixed by means of a hinge assembly 20 on the support frame 19 and by means of hydraulic cylinder 21 about the hinge axis 22 of this hinge assembly 20 are pivotable, while the remaining frame 18 on the support frame 19 are arranged rigidly.

Die Hydraulikzylinder 9 und 9' sind als Druckausgleichssystem 10,10' zwischen den einzelnen reifenartigen Elementen 8 ausgebildet. Die Hydraulikzylinder 9 und 9' sind jeweils zwischen dem Rahmen 18 und den Tragarmen 7 angeordnet. Das Druckausgleichssystem weist, wie Fig. 5 zeigt, die beiden Druckausgleichskreise 10 und 10' auf. In diesen Druckausgleichskreisen 10 und 10' des Druckausgleichssystems sind die Sperrventile 12 und 12' angeordnet. Die dem Fahrwerk 11 zugeordneten Hydraulikzylinder 9' sind mittels der Sperrventile 12, 12' gegenüber den anderen Hydraulikzylinder 9 der Druckausgleichssysteme 10 und 10' absperrbar.The hydraulic cylinders 9 and 9 'are formed as a pressure equalization system 10,10' between the individual tire-like elements 8. The hydraulic cylinders 9 and 9 'are respectively disposed between the frame 18 and the support arms 7. The pressure compensation system has, as Fig. 5 shows, the two pressure compensation circuits 10 and 10 'on. In these pressure compensation circuits 10 and 10 'of the pressure compensation system, the check valves 12 and 12' are arranged. The chassis 11 associated hydraulic cylinder 9 'by means of the check valves 12, 12' relative to the other hydraulic cylinders 9 of the pressure compensation systems 10 and 10 'shut off.

Zwischen den Rahmen 18 und dem Tragrahmen 19 sind für die das Fahrwerk 11 bildende Reifenelemente jeweils zumindest ein doppeltwirkender Hydraulikzylinder 21 angeordnet, die über Leitungen mit einem Hydrauliksystem 23, wie Fig. 5 zeigt, verbunden sein.Between the frame 18 and the support frame 19, at least one double-acting hydraulic cylinder 21 are arranged for each of the chassis 11 forming tire elements, which via lines to a hydraulic system 23, such as Fig. 5 shows, be connected.

In Arbeitsposition der Walze 16 und der Säschare 17 sind die Hydraulikzylinder 21 eingefahren und die Absperrventile 12, 12' geöffnet, so dass die Reifenelemente 8,8' und die Säschare 17 sich in den Positionen befinden, wie es die Fig. 6 bis 8 zeigen.In the working position of the roller 16 and the coulters 17, the hydraulic cylinders 21 are retracted and the shut-off valves 12, 12 'open, so that the tire elements 8,8' and the coulters 17 are in the positions as it Fig. 6 to 8 demonstrate.

Um die Säschare 17 und die Reifenelemente 8' in Transportposition zu bringen, werden zunächst die Absperrventile 12,12' geschlossen, so dass die als Fahrwerk 11 dienenden Reifenelementen 8' zugeordnete Hydraulikzylinder 9' gegenüber den übrigen Reifenelementen 8 zugeordneten Hydraulikzylindern 9 abgesperrt sind. Anschließend wird über die Hydraulikanlage 23 den Hydraulikzylindern 21, die zwischen dem Tragrahmen 19 und dem Rahmen 18 angeordnet sind, mit Druck beaufschlagt, so dass sie ausgefahren werden. Hierdurch verschwenken die Hydraulikzylinder 21 die Rahmen 18 in die den Fig. 9 bis 11 gezeigten Positionen, so dass die das Fahrwerk 11 bildenden Reifenelemente 8' gegenüber den übrigen Reifenelementen 8 nach unten gedrückt werden. Hierdurch werden die nicht das Fahrwerk 11 bildenden Reifenelemente 8 und der Rahmen 18 sowie der Tragrahmen 19 angehoben. Gleichzeitig werden auch die den das Fahrwerk 11 bildenden Reifenelemente 9' zugeordneten Säscharen 17 durch Verschwenken des Rahmens 18 nach oben geschwenkt, wie insbesondere die Fig. 9 und 10 zeigen.In order to bring the coulters 17 and the tire elements 8 'in transport position, the shut-off valves 12,12' are initially closed, so that the hydraulic cylinders 9 'assigned to the tire elements 8' serving as running gear 11 are shut off from the other tire elements 8 associated hydraulic cylinders 9. Subsequently, via the hydraulic system 23, the hydraulic cylinders 21, which are arranged between the support frame 19 and the frame 18, pressurized, so that they are extended. As a result, the hydraulic cylinders 21 pivot the frame 18 in the Fig. 9 to 11 shown positions, so that the chassis 11 forming tire elements 8 'relative to the other tire elements 8 are pressed down. As a result, not forming the chassis 11 tire elements 8 and the frame 18 and the support frame 19 are raised. At the same time the the chassis 11 forming the tire elements 9 'associated coulters 17 are pivoted by pivoting the frame 18 upwards, in particular the Fig. 9 and 10 demonstrate.

Um die Walze aus den in Fig. 9 bis 11 dargestellten Transportposition in die in Fig. 6 bis 8 dargestellte Position zu bringen, werden die Hydraulikzylinder 21 entgegengesetzt durch Umschalten des Umschaltventils der Hydraulikanlage 23 mit Druck beaufschlagt, so dass die Hydraulikzylinder 21 einfahren. Hierdurch wird der Rahmen 18' in die in Fig. 6 bis 8 dargestellte Position verschwenkt. Anschließend werden die Absperrventile 12,12' in dem Druckausgleichssystem 10,10' geöffnet, so dass insgesamt alle Hydraulikzylinder 8,8' wieder in das Druckausgleichssystem 10, 10' integriert sind.To get the roller out of the in Fig. 9 to 11 shown transport position in the in Fig. 6 to 8 To bring shown position, the hydraulic cylinder 21 are oppositely pressurized by switching the switching valve of the hydraulic system 23, so that the hydraulic cylinders 21 retract. As a result, the frame 18 'in the in Fig. 6 to 8 shown pivoted position. Subsequently, the shut-off valves 12, 12 'are opened in the pressure equalization system 10, 10' so that, overall, all the hydraulic cylinders 8, 8 'are integrated again into the pressure equalization system 10, 10'.

In nicht dargestellter Weise können auf der Rückseite der das Fahrwerk 11 bildenden Reifenelementen 8' Abstreifer angeordnet sein. Diese Abstreifer streifen die an der Lauffläche der Reifenelemente 8' oder zwischen diesen anhaftenden Bodenteile ab.In a manner not shown can be arranged on the back of the chassis 11 forming tire elements 8 'scraper.
